During our time in Berlin we managed to make it out for a pub crawl (which btw was awesome and lasted till 4 a.m., but that's a whole other story), where we met some interesting people from all over the world. Anyone we'd talk to that night seemed to have the same opinion of Prague.. it's gorgeous, truly, but it's even more incredible during the night. Not taking our new-found friends' advice for granted, we took a nap after exploring Prague by day, and ventured out into the starry night. Wow.. what a sight... Prague is truly magical, any time of the day.
P.S. If you're planning a trip to any of the major cities in Europe (Berlin, Prague, Madrid, etc.), and are looking to party, check out SANDEMANs NEW Europe tours. They offer awesome nightly get-togethers as well as free walking tours by day!
